SPRING-OILER.

Application filed June 25, 1918.

To all whom it may concern:

Be it known that I, ALBERT ROY GIRTON, residing a Bloomsburg, Columbiacounty, State of Pennsylvania, and being a citizen of the United States,have invented certain new and useful Improvements in Spring- Oilers, ofwhich the following is a full, clear, and exact description, such aswill enable others skilled in the art to which it appertains to niakeand to use the same, reference being had to the accompanying drawings,which illustrate the preferred form of the invention, though it is to beunderstood that the invention is not limited to the exact details ofconstruction shown and described, as it is obvious that variousmodifications thereof within the scope of the claims will occur topersons skilled in the art.

In said drawings:

Figure 1 is a Vertical sectional view of a wheel and bearing showing thedevice in elevation;

Fig. 2 is a side elevation;

Fig. 3 is a longitudinal sectional view;

Fig. 4 is an end elevation looking at the ingress port;

Fig. 5 is an end elevation looking at the opposite end or egress port;and

Fig. 6 is a longitudinal sectional view be fore bending the fingers orassembling the spring and valve.

The purpose of the invention is to provide a lubricating device ofsimple construction, wherein use is made of cheap and easilymanufactured parts capable of ready assembly with a minimum expenditureof labor, and one that will have, substantially, a clear andunobstructed passage thercthrough at predetermined times.

To provide for such simple construction and assembly, it is proposed tomake the casing hollow and of ductile material and to form slots thatextend longitudinally from one end through the major portion of thelength of the casin and thus produce bendable extensions or nngersbetween the slots.

The passage through the casing is provided with a constricted portionhaving a valve seat formed on one side and the opposite side is flaredor curved to form a lubricant ingress port. To close and control theport, an approximately disk-like valve, hav- Specification of LettersPatent.

ing convex and concave faces or sides is employed.

To maintain the valve in its operative position, a spring is used whichhas one of its ends seated in the concavity of the valve, and when theextensions or fingers are bent inwardly toward each other until they arein contact, the slots have their open ends closed and a seat is formedby the inner wall of the converging fingers for the other end of thespring. Thus the valve and spring are retained within the, casing. Oneend of the casing is provided with a toolengaging portion and also witha section adapting the oiler to be removably secured in position, as,for example, in a car wheel.

In the embodiment shown, the casing A may be formed of any suitablematerial, which is preferably ductile,-so that the various operations ofmanufacture and assembly will result in its being properly made. Thiscasing is hollow and the passage therethrough is of difierent diametersdue to the convergence of the walls extending inwardly from the valveseat.

As shown in Fig. 3, at the right hand side, the passage terminates in aningress port 10 that is provided with an outwardly flaring or curvingwall 11'. This produces a configuration that is similar to the mouth ofa bell and facilitates the entrance of a nozzle of a grease gun. Theinner end of the flared portion has an opening 12 that constitutes theinner end of the port 10.

The inner wall of the passage on the opposite side this opening 12 alsoflares or curves outwardly, and is preferably so formed that ahemispherical valve seat 13 is produced. From adjacent the valve seat13, inwardly, the wall of the casing is relatively thin, and beginningat a point near where the largest diameter of the valve seat merges intothe wall of the casing, open-ended slots 14:, 15, 16 and 17 are formed.These slots extend longitudinally through the major portion of thelength of the casing A to within a short distance from the valve B andare spaced circumferentially.

Between each of the slots 14:, 15, 16 and 17 suiiicient material is leftto form fingers or extensions 18, 19, 20 and 21. As these fingers orextensions are parts of a circle they are therefore segmental orarouate. As

" the casing A is preferably of malleable iron,

. port 10, a spring 25 is used.

face 22 that is adapted to closely conform to the valve seat 13, whileits opposite face is provided with a concavity or depression 23 whichserves as a spring seat. The valve also has a-cylindrical portion 21.The preferred shape of the valve 13 is shown in Fig.

3, and is ge'nerally concavo-convex.

In order that the valve B may be normally maintained on its, seat 13 forclosing the opening 12 and controlling the ingress This spring i may beof any variety of the helical type and is so formed that one end willseat in the concavity 23 or press against the valve B.

To maintain, the spring 25 in position within the casing A, the fingersor extensions18, 19, 20 and 21 have their free ends bent inward towardeach other. This bending is continued until the sides of the slotsadjacent their open ends are incontac't, as shown in Figs. 1,2, 3 and 5,thus closing the slots. These slots, when closed, have an ogival shape,or in other words, their longi: tudinal sides converge. At the sametime,

the free ends being arcuate in shape fona an approximately round openingG atthe end of the casing which serves as a lubri cant egress port. Theslots will also serve as lubricant egress ports so that whateverlubricant enters the ingress port 10 will freely passtothe bearing orinto the reservoir provided;

Externally, at one end of the casing A, there is formed a hexagonaltool-engaging portion D. The casing, is also provided with the screwthreads E so that the device may be interlocked with a bearing, thethreads adapting the device to be removably secured in 'an' operativeposition. I

It will be noticed that the fingers 18, 19, 20 and 21' form ataperedportion extending from the threads E. The tap'ering of the innerwall of the fingers provides a means for retaining the spring inposition, as one end of the spring bears against said nearthe inner endofthe casing.

To assemble the device, the valve and its spring are inserted into thecasing, the open or inner end is set ona suitable concave seat and thefingers 18 to 21 are caused to 0on wall verge by a suitable blow on theouter end D thereby looking all the parts in assembled relation.

Various diameters 'of wire may be used in forming the spring inconformity w th the type of lub'rica'nt employed; 7

From the above description of the'lub'ricating device, it will beseen-that it em-, bodies a very slmple construction and oneof itsadvantages lies in the fact that the interior of the casing issubstantially clear and free of obstructions, such as a valve stem. Thispermits the casing to receive a larger quantity of lubricant than isusual, and with the elimination of space occupying members, allows thelubricant to freely pass to the bearing without oozing outward past thevalve and through the ingress port 10.

It will be observed that the casing is slotted longitudinally from itsinner end almost to the valve seat at its outer end and a slightmovement of the valve inwardly will permit ingress of lubricant, whichmay be fluid oil or heavy grease, and immediately such lubricant willfind uninterrupted egress passage through the longitudinal slots.
